Cobblemon Otherside Spawns

Cobblemon spawns for the Otherside dimension from the mod Deeper and Darker. This pack's spawns should work for versions 1.20.1-1.21.1. I also added functionality that makes it so sculk mobs in the Otherside dimension do not target cobblemon, however this only works with the 1.21.1 version of the Deeper and Darker mod, as that is the version in which they added the necessary mob type tag.
